On the season, Schofield has four sacks and 34 total tackles — good for fourth-best on the team.

The injury is especially painful for the Cardinals, who are rather thin at the position. Quentin Groves — two sacks and 17 tackles — has played admirably as Schofield’s backup, but after that it’s slim pickings for Arizona.

Zach Nash, a rookie, was activated off the practice squad this week, and was third on the depth chart behind Schofield and Groves against the Packers.

Inside linebacker Stewart Bradley has seen very limited time this season, but was used on the outside during certain packages last year.
